Britton Reviewed by James Sneyd 2003. 92 figures. 335pp. Springer-Verlag. Softcover. ISBN 1-85233-536-X Because the mathematical biosciences have come into such high fashion (for which fact, trust me, I make no complaint) there has arisen a demand for courses in mathematical biology, courses that will introduce mathematically inclined students to the delights of the other side. Such courses come in many different flavours, as many as there are teachers one imagines. Some are aimed at biology students also, some at bioengineers or other engineering students, while others are aimed more strictly at mathematics majors, to give them a flavour of biological applications while still teaching them mathematical techniques. It is this latter kind of course at which Britton's book is aimed. When I first picked up the book and skimmed through it, I was left with the superficial impression that it is just Jim Murray without the steroids. After all, Murray's book [1] is one that you could kill with. Literally. (I'm thinking here of tying the volumes together and dropping them from a height. If you did this with Britton's book, it would hardly raise a bump on a student's head. I hasten to add that I haven't yet tried either of these things.) Britton's book goes through the usual topics of population dynamics, a bit of genetics, infectious diseases, biological motion (diffusion, dispersion, chemotaxis, etc), basic enzyme kinetics, reaction-diffusion equations and pattern formation, mechanochemical models, and tumour models. It covers these topics briefly, with minimal digression, the end result being a relatively small book, containing material that could reasonably be covered in a couple of one-semester courses. The focus is entirely on deterministic modeling, and there is no discussion of computational methods. However, to condemn "Essential Mathematical Biology" just because you couldn't kill someone with it would be to do it a grave disservice, for in brevity and simplicity lies the great strength of this book. It explains its chosen topics clearly and simply, not including extraneous material, and is written at a level that can be understood and appreciated by undergraduate students. Indeed, the level of writing is superb in its clarity and elegance. For this reason it has become a popular teaching text in the UK, as I have been reliably informed. Rather than having to use Murray's wonderful tome (tomes now, I should say), teachers can use a smaller book, containing the essential material, and at the right level and quantity. Just as useful as the writing style are the appendices and the hints. Not only does Britton give elementary presentations of some basic mathematical techniques (difference equations, ODEs and PDEs) he also gives extensive hints for the exercises, bordering on complete solutions in some cases. This is a resource that will surely prove extremely useful for all teachers of such a course. There is even an accompanying web page ( http://www.maths.bath.ac.uk/~nfb/book/) in which additional material may be found, although limited in extent as yet. So, given the manifold strengths of this book, why would I not use it myself? Well, I can hardly help feeling that, if you want to teach students how to apply math to biology, you really need an awful lot more biology than is given here. As a reviewer, I get to air my pet gripes, and this is one of them. (I have others, so don't ask.) Why should we teach students 82 pages of population dynamics, 30 pages of Turing instabilities, and 6 pages of neuroscience? Isn't this a little lop-sided? Isn't neurophysiology one of the few areas in which the data is quantitative and reproducible, the models well-developed, and the connection between the two explicit? Has anyone yet measured activator and inhibitor concentrations in embryological systems, or is it still in the realm of mathematical fairy tales? Should we really be training math students to believe that an analysis of the Lotka-Volterra equations is mathematical biology? Personally, I believe not. Where does this leave mathematical biology courses, then? Well, I don't think there really is a good book for undergraduate mathematical biology as yet. The books by Murray [1] and Keener and Sneyd [2] are just too thick and heavy, being designed more as graduate texts. Edelstein-Keshet [3] is more of a mathematics book than anything else, although it does an excellent job in many ways. Hoppensteadt and Peskin [4] contains a lot of interesting material (and I have taught from this book myself a number of times) but is more like two books in one, as is the edited book by Fall et al. [5]. Taube [6] has considerable merit, particularly in his unique method of presentation, but is not always suitable for teaching undergraduate mathematics students. Each of these books has strengths and weaknesses, but not one of them covers a broad range of mathematical biology, including computation, data and modeling, at a level and length appropriate for a typical upper-level undergraduate course. I suppose that, in some ways, the search for the perfect book is a futile one; the field of mathematical biology is now so vast and varied, that it is impossible to do it justice, and please every reviewer, in a single undergraduate text. Nevertheless, my personal prejudices aside, there is no denying that "Essential Mathematical Biology" is superbly designed for the purpose it serves, and will, I am sure, become a popular text book across the world.

Murdock By Mark Groves Springer Monographs in Mathematics, Springer-Verlag 2003. Normal-form theory has become a celebrated topic which is widely used in nonlinear science. Its basic application is the classification of dynamical systems into categories by transforming nonlinear vector fields into a standard form which is determined by their linear part; one expects that the solution sets of those dynamical systems whose vector fields lie in the same category should exhibit similar features. In essence, the vector field is expanded in a power series and a sequence of near-identity transformations is constructed which systematically remove `non-resonant' homogeneous quadratic, cubic, quartic, ... terms without affecting those of lower order; the definition of the term `non-resonant' is part of the theory. The resulting vector field is said to be in normal form up to a certain order, and up to this order contains only `resonant' terms. The book under review is chiefly concerned with the mechanics of carrying out this procedure. The author uses terminology which I have not seen elsewhere (and avoids the words `resonant' and `non-resonant' as much as possible). The procedure of constructing and handling the near-identity transformations is called a `normal-form format.' For example, one can use a single transformation with coefficients determined recursively or a sequence of transformations applied iteratively, and the transformations can be constructed directly or via auxiliary generating functions; the author discusses five such normal-form formats in detail. Regardless of how the actual transformation theory is organised, each step of the normal-form theory requires the solution of an inhomogeneous linear equation for the homological operator £ (which is fixed by the chosen normal-form format) in the space of homogeneous polynomials of the relevant order. To solve the equation it is necessary to write this space as the direct sum of the range of £ and a complement, the precise choice of which is called the `normal-form style.' The author treats five normal-form styles, which he terms semisimple (applicable only when the linear part of the vector field is associated with a semisimple matrix), extended semisimple, inner product (previously championed by G. Elphick and G. Iooss), simplified and sl(2) (previously championed by R. Cushman and J. Sanders). The choice of a normal-form format and style completely determines the normal form, and there remain the tasks of characterising the terms in the transformed vector field (the `description problem') and calculating their coefficients (the `computation problem'). After some introductory examples, the author begins his treatment in Chapter 2 with a detailed discussion of the `splitting problem', that is the task of finding a direct-sum decomposition of a vector space V into the range of a linear operator L on V and a suitable complement. Several choices of complement are discussed which later evolve into the `normal-form styles' (splittings associated with the homological operator £) discussed above. The following Chapters 3 and 4 on respectively linear and nonlinear normal forms make up the heart of the book. Chapter 3 is dedicated to normal forms related to unfoldings of linear vector fields. At issue is a linear vector field depending upon a parameter ε the vector field is expanded in a power series in ε and the normal-form theory is used to remove non-resonant terms in the higher-order ε-dependent terms. Many of the ideas used in subsequent chapters are introduced and developed here (and in lengthy appendices), in particular a thorough explanation of five `normal-form formats' (transformation theories) and the use of `normal-form styles.' This material is expanded into full nonlinear normal-form theory in Chapter 4, where the description and computation problems are also comprehensively discussed. Ring and module theory are brought to bear on the former, while algorithmic methods suitable for symbolic computation are developed for the latter. The final two chapters are devoted to some central applications of nonlinear normal forms. One of the great advantages of `truncated normal forms' (obtained by placing a vector field into normal form up to a certain order and dropping higher-order terms) is that their geometrical structures such as stable, unstable and centre manifolds and fibrations of the centre-stable and centre-unstable manifolds over the centre manifold assume an obvious, almost explicit structure and are readily discussed. (Indeed, `truncated normal forms' are often completely integrable.) Chapter 5 presents a detailed discussion of this feature and addresses related approximation issues: how well does for example the centre manifold of a truncated normal form approximate the centre-manifold of the vector field obtained by adding higher-order terms? Finally, in Chapter 6, the author turns to local bifurcation theory in which local bifurcation problems are studied using normal forms. The emphasis here is upon the classical unfolding situation in which a parameter is varied so that the nature of the linear part of the vector field near the origin changes, and associated steady-state, periodic or homoclinic bifurcation is detected according to the signs of certain coefficients in an appropriate nonlinear normal form. The key fact here is that only a small number of coefficients of low-order terms is required to settle the issue (for the `full' vector field as well as the `truncated normal form'), and the author explains the use of `Newton diagrams' to indicate which coefficients are important in this respect. This book certainly represents a very thorough treatment of the anatomy of normal-form transformations; in addition to the detailed explanations of normal-form `formats' and `styles' there is a comprehensive explanation of canonical forms for matrices (for example the Jordan canonical forms), a detailed algorithmic approach to the `description' and `computation' problems and two lengthy appendices on ring and module theory. It may serve well as a reference work on this aspect of normal-form theory, and indeed the author achieves his stated aim of providing an encyclopedia of results and explanations which are not easily found in the existing literature. Given this thoroughness, it is perhaps surprising that, with the exception of the rather cursory Section 4.9 on Hamiltonian systems, the author does not present a systematic treatment of normal forms for vector fields with symmetries. (Incidentally, I disagree with his statement that `an inner-product normal-form style for the Hamiltonian case has not been worked out' - it is presented in detail by Elphick (`Global aspects of Hamiltonian normal forms,' Phys. Lett. A 127, pp. 418--424, 1988) and Meyer & Hall (`Introduction to Hamiltonian dynamics and the N-body problem,' Springer-Verlag, 1992, Section VII.C.2).) I suspect that the book is, however, unlikely to be of interest to the core readership of UK Nonlinear News whose primary interest is in the use of normal forms as a tool for the analysis of phenomological problems. These readers would be more interested a book which catalogues the solution to the `description problem' for normal forms in a wide range of unfolding scenarios (which goes far beyond the limited number of more or less standard examples presented here) together with a list of `tips and tricks' for computing important coefficients as efficiently as possible (rather than an algorithmic procedure). In this respect a book such as Topics in Bifurcation Theory and Applications by G. Iooss & M. Adelmeyer, World Scientific, in which a normal form with an `inner product style' is developed and applied to a large number of unfolding scenarios, would be much more helpful.

If the answer is yes this is the book to look at. The book is written by physicists with a pragmatic audience in mind. It contains a very thorough and clearly written discussion of the mathematical foundation as well as the applications to important and interesting mathematical and physical problems. All the topics are very main stream and of great general relevance. The authors approach is guided by their observation that the calculus invented by Newton's and Leibniz's for smooth functions is simply not able to describe the non-analytic nature of many very important and common cases. The simplest and probably most wide spread of such examples is the trajectory of a Brownian particle or a random walker. The usual integer derivative is simply to be considered as a special case of a much larger, and more powerful, class of derivatives. It is curious to learn on page 1 that Leibniz himself in 1695 considered how to define the 1/2-power derivative of a monomial. Clearly, the non-integer derivatives are not just the latest fashion. Although the authors open the book with the words: "This is not a text book", it could certainly serve the purpose as an excellent introductory text accompanying a course, say, on Dynamics either in Applied Mathematics or in Physics. The book is so carefully explain and so impressively comprehensive that it would be excellent an undergraduate as well as graduate course - one would, though, have to construct problems for the class since no the book contains no problems or questions at all. Obviously, the book is also of great relevance to the researcher who may need to become acquainted with Fractal Calculus in order to consider if Fractal Calculus is useful to whatever problem one is currently involved with in Statistical Mechanics, Complex Systems, Dynamical Systems etc. The book starts out with two chapters in which the shortcomings of integer derivatives are discussed. Here, as in the rest of the book, physical and mathematical arguments are presented in parallel. To me this makes the reading more easy and enjoyable. Having realised the inadequacy of ordinary calculus we are now primed for the presentation of Fractal Calculus. This is done in the next three chapters where we learn about the elementary properties of fractal derivatives, generalised exponential and trigonometric functions. Fractal Fourier and Laplace transforms are introduced next in a reasonably self-contained way. A student won't really need to know much about either Fourier or Laplace transforms before hand. All the most important properties are introduced. Constantly many relevant and illuminating comments are given and each chapter contains a bibliography to the most essential papers and books. The second half of the book contains the discussion of the applications of Fractal Calculus. There are three chapters of which the first is on Fractal randomness. The chapter focuses on random walks, stochastic time series and evolution equations (Fokker-Planck and Levy) for probability densities. The second application chapter is concerned with Fractal Rheology, i.e. a topic from materials science. Although this might sound a bit engineering like and therefore an unlikely arena for the demonstration of a new and advanced type of calculus, we are in fact here presented with concepts such as fractal memory, fractal viscoelasticity as well as path integrals. One is explained how fractal derivatives enables a quantitative description of stress relaxation experiments. The third of the application chapters discuss Gaussian processes which are non-Markovian due to long-time memory with a focus on fractal Brownian motion as introduced by Mandelbrot and van Ness. The last chapter is concerned with fractal propagation which leads to fractal eigenvalue problems and the fractal oscillator among other topics. I am glad I got to know this book. I don't know yet whether fractal calculus will be of crucial importance to my own research in statistical mechanics and complex systems. But I got the feeling from this book that this might very well be the case. And if this happens, I now know exactly where to go for a highly readable and thorough introduction to the field. I think the book deserves to be present in mathematics and physics libraries. And I believe many interesting undergraduate and graduate projects in mathematics and its applications can start out from this book. I have one little complaint. We all think of Springer as producing extremely high quality, and rather costly, books. The content of this book is first class, but I find it a bit surprising that the quality of the printing of the figures is so far below the quality of the printed text. Perhaps the book was produced entirely by the (in that case very careful) authors without the involvement of a copyeditor? I found one typo that indicates this: namely a "[?]" (on p. 249) instead of a reference number. This is of course what often happens when we use LaTex and is normally spotted by the copyeditor. Nevertheless, get hold of the book for its exciting and well presented content. If you can't afford the book for yourself, then try to get it for a library near you.

The MSc course in Data Analysis, Networks and Nonlinear Dynamics equips students with the mathematical, statistical and computing skills that are essential to the analysis and understanding of complex processes and communication systems. These skills are in very short supply throughout industry, commerce and the public sector. The MRes course Mathematics in the Living Environment is a joint course with the Department of Biology and about 50% is taught with the above MSc. The course teaches students the mathematical and biological skills needed to contribute effectively to the investigations of the complex interactions in living systems. Both courses are seeking candidates with good degrees in Mathematics or other disciplines with a strong Mathematical content. A number of funded places are available for suitably qualified candidates. Further details are in the following web pages.

Indeed calcium signals in the form of waves have been the subject of much recent experimental interest. A fundamental approach for studying cellular signalling is the combination of state of the art experimental techniques, in particular high resolution fluorescence imaging, with spatio-temporal mathematical models of intracellular calcium regulation. Experimental findings can be incorporated into mathematical models and, vice versa, model predictions can be directly tested in experiments. This approach provides a powerful tool to clarify the very complex mechanisms involved in cellular Ca2+ signalling. The aim of this thesis is to provide insight into oscillations and waves of cytosolic Ca2+ in both single and multi-cellular systems from a mathematical perspective. We focus on two models of Ca2+ release for a systematic mathematical and numerical analysis of Ca2+ dynamics. One of them is a biophysically detailed model which we study using tools from bifurcation theory, numerical continuation and numerical simulation. The other is a much simpler minimal model of Ca2+ dynamics that emphasises the fundamental space and time scales of cellular Ca2+ dynamics and allows for exact mathematical analysis. For the detailed biophysical model we calculate the speed and stability of travelling waves as a function of physiologically significant parameters. The minimal model of Ca2+ dynamics is obtained via a systematic reduction of the biophysical model and its analytically obtained behaviour is shown to be in excellent agreement with the original biophysical model. This minimal model is then used to gain insight into the effects of spatial heterogeneity and biologically realistic sources of noise on intra- and inter-cellular cell signalling. In particular we pursue issues of wave propagation, wave propagation failure and the role of noise in generating coherent whole cell rhythms.

It is anticipated that one of these studentships will include a CASE award with the UK Met Office. The research will focus on the assimilation of data into numerical weather prediction models. Errors that occur in specifying the initial conditions are responsible for the majority of poor forecasts, and there is a premium in the optimal exploitation of observational data. Most operational forecasting centres now use variational techniques and control theory as a basis for their data assimilation, and these studentships will study techniques for incorporating constraints, which are designed to minimize the growth of spurious modes, into the variational schemes.The research will provide the students with an excellent introduction to control theory, stochastic differential equations and numerical modelling.

Pojman and Qui Tran-Cong-Miyata Despite the great strides in nonlinear dynamics over the past 40 years, applying nonlinear dynamics to polymeric systems has not received much attention. This book addresses this absence by covering present theory, modeling, and experiments of nonlinear dynamics in polymeric systems. Oscillating chemical reactions, propagating fronts, far-from equilibrium pattern formation, Turing structures, and chaos are but some of the exotic phenomena discussed in this book. The book is the result of the Symposium on Nonlinear Dynamics in Polymeric Systems sponsored by the Division of Polymer Chemistry and the Division of Physical Chemistry at the August 18-22, 2002 American Chemical Society National Meeting in Boston.

Cerveau, E. Ghys, N. Sibony and J-C Yoccoz In the last twenty years, the theory of holomorphic dynamical systems has had a resurgence of activity, particularly concerning the fine analysis of Julia sets associated with polynomials and rational maps in one complex variable. At the same time, closely related theories have had a similar rapid development, for example the qualitative theory of differential equations in the complex domain. The meeting, "Etat de la recherche", held at Ecole Normale Supérieure de Lyon, presented the current state of the art in this area, emphasizing the unity linking the various sub-domains. This volume contains four survey articles corresponding to the talks presented at this meeting. D. Cerveau describes the structure of polynomial differential equations in the complex plane, focusing on the local analysis in neighborhoods of singular points. E. Ghys surveys the theory of laminations by Riemann surfaces which occur in many dynamical or geometrical situations. N. Sibony describes the present state of the generalization of the Fatou-Julia theory for polynomial or rational maps in two or more complex dimensions. Lastly, the talk by J.-C. Yoccoz, written by M. Flexor, considers polynomials of degree 2 in one complex variable, and in particular, with the hyperbolic properties of these polynomials centered around the Jakobson theorem. This is a general introduction that gives a basic history of holomorphic dynamical systems, demonstrating the numerous and fruitful interactions among the topics. In the spirit of the "Etat de la recherche de la SMF" meetings, the articles are written for a broad mathematical audience, especially students or mathematicians working in different fields. This book is translated from the French edition by Leslie Kay.

Bartusek, Z. Doslá and J.R. Graef First posed by Hermann Weyl in 1910, the limit-point/limit-cycle problem has inspired, over the last century, several new developments in the asymptotic analysis of nonlinear differential equations. This self-contained monograph traces the evolution of this problem from its inception to its modern-day extensions to the study of deficiency indices and analogous properties for nonlinear equations. With over 120 references, many open problems, and illustratice examples, this work will be valuable to graduate students and researchers in differential equations, functional analysis, operator theory, and related fields. 2003, 140pp, 10 illustrations ISBN 0-8176-3562-9. A Stability Technique for Evolution Partial Differential Equations: A Dynamical Systems Approach V.A. Galaktionov and J.L. Vazquez This book presents a new method for studying the asymptotic behaviour of solutions to evolution partial differential equations; much of the text is dedicated to the application of this method to a wide class of nonlinear diffusion equations. The Stability Theorem, on whih the method hinges, is examined in the first chapter, followed by a review of basic results and methods - many original to the authors - for the solution of nonlinear diffusion equations. Further chapters provide a self-contained analysis of specific equations and their applications, along with carefully-constructed theorems, proofs, and references. 2003, 430 pages, 10 illustrations ISBN 0-8176-4167-7 Progress in Nonlinear Differential Equations and their Application ------------------------------------------------------------------------ New from Cambridge University Press * Mathematical Models in Biology ------------------------------------------------------------------------ Mathematical Models in Biology E.S. Allman and J.A.

ISBN 0-521-81980-6 Hardback ISBN 0-521-52586-1 Softback ------------------------------------------------------------------------ New from Princeton University Press * Entropy ------------------------------------------------------------------------ Entropy Edited by Andreas Greven, Gerhard Keller, and Gerald Warnecke The concept of entropy arose in the physical sciences during the nineteenth century, particularly in thermodynamics and statistical physics, as a measure of the equilibria and evolution of thermodynamic systems. Two main views developed: the macroscopic view formulated originally by Carnot, Clausius, Gibbs, Planck, and Caratheodory and the microscopic approach associated with Boltzmann and Maxwell. Since then both approaches have made possible deep insights into the nature and behavior of thermodynamic and other microscopically unpredictable processes. However, the mathematical tools used have later developed independently of their original physical background and have led to a plethora of methods and differing conventions. The aim of this book is to identify the unifying threads by providing surveys of the uses and concepts of entropy in diverse areas of mathematics and the physical sciences. Two major threads, emphasized throughout the book, are variational principles and Ljapunov functionals. The book starts by providing basic concepts and terminology, illustrated by examples from both the macroscopic and microscopic lines of thought. In-depth surveys covering the macroscopic, microscopic and probabilistic approaches follow. Part I gives a basic introduction from the views of thermodynamics and probability theory. Part II collects surveys that look at the macroscopic approach of continuum mechanics and physics. Part III deals with the microscopic approach exposing the role of entropy as a concept in probability theory, namely in the analysis of the large time behavior of stochastic processes and in the study of qualitative properties of models in statistical physics. Finally in Part IV applications in dynamical systems, ergodic and information theory are presented. The chapters were written to provide as cohesive an account as possible, making the book accessible to a wide range of graduate students and researchers. Any scientist dealing with systems that exhibit entropy will find the book an invaluable aid to their understanding.

Ottesen, M.S. Olfusen and J.K. Larsen This book introduces mathematicians to real applications from physiology. using mathematics to analyze physiological systems, the authors focus on models reflecting current research in cardiovascular and pulmonary physiology. In particular, they present models describing blood flow in the heart and in the cardiovascular system, as well as the transport of oxygen and carbon dioxide through the respiratory system and a model for baroreceptor regulation. Applied Mathematical Models in Human Physiology is the only book available that analyses up-to-date models of the physiological system at several levels of detail. Some are simple `real-time' models that can be directly used in larger systems, while others are more detailed `reference' models that show the underlying physiological mechanisms and provide parameters for and validation of simpler models. The book also covers two-dimensional modeling of the fluid dynamics in the heart and its ability to pump, and includes a discussion of modeling wave-propogation throughout the systemic arteries.

To a large extent this has arisen due to the pervasiveness of the soliton concept, demonstrated by the ubiquity of such model equations as the Korteweg-de Vries equation and the nonlinear Schrodinger equation. The aim of this week-long course is to present the basic paradigms of nonlinear waves in fluids, describe how these paradigms have been built on and developed emphasising the most recent work, and how the modern theory is used to understand and inform observations and numerical simulations. Course Outline: The lectures will cover asymptotic methods of derivation of canonical evolution equations, such as those belonging to the Korteweg-de Vries type, the wave packet equations developed from the nonlinear Schrodinger model, the resonant wave interaction equations and the Zakharov kinetic equations, descriptions of the basic solution techniques, both analytical and numerical, of these evolution equations, and the most relevant and compelling modern applications. These themes are interlocked, and this will be demonstrated throughout the lecture series. The lectures will focus on applications in fluids, with a strong emphasis on inviscid flows, and a bias towards geophysical applications. The course will be composed of 4 days of lectures, followed by a 1/2-day workshop session.
